Fiied Dec. 10, 1963, Ser. No. 329,566 2 Claims. (Cl. 6153) Thisinvention relates generally to the art of piling and more particularlyto a drive-fit sectional transition sleeve for connecting pipe or shellsections of varying diameters.

Piles are used to support or to form foundations for structures such asbuildings, banks, bnidges, conduits, piers, wharves, etc. by insertingthe piles int-o or through the yielding surface strata far enough toobtain a solid support for the principal structure. A compositestructure is ordinarily used for this purpose.

One of the problems in piles of this type is that of joining a tubularpile section of one diameter to a tubular pile section of a differentdiameter.

An important object of the present invention is to provide a sectionaldrive-fit transition sleeve for eliminating the above problem.

Another object of the invention is to provide a sectional transitionsleeve for joining tubular pile sections that has a high resistance tolateral and tensional stresses and forces as well as compressionalforces.

It is a specific object of the invention to provide a sectionaltransition sleeve having a narrow section serving as a plug and having awider section serving as a socket for joining tubular pile sections ofdifferent diameters in offset relation.

It is also an object of the invention to provide a sec tional transitionsleeve for joining tubular pile sections that is economical tomanufacture, rugged in construction and is highly eflicient for thepurpose intended.

Broadly the invention consists of a transition sleeve constituted by apair of flanged pipes telescoped one 'within the other and force fittedto each other, one pipe constituting a socket and the other a plug, theflange of the socket member having a larger diameter than the diameterof the flange of the plug member whereby pile sections of varyingdiameters may be connected in offset relation.

For further comprehension of the advantages and benefits of theinvention, reference will be had to the accompanying drawing forming amaterial part of this disclosure, whe-rein FIG. 1 is a side elevationalview of a fragment of a pile with a transition sleeve joining the upperand lower tubular pile sections, said sleeve embodying one form of theinvention.

FIG. 2 is a vertical sectional view taken on the line 2 2 of FIG. 1.

FIG. 3 is a view as seen from the line 3-3 of FIG. 1, looking in thedirection of the arrows.

FIG. 4 is a view as seen from the line 3-3 looking downwardly.

FIG. 5 is a sectional view similar to FIG. 2 of a transition sleeveembodying a modified form of the invention, the tubular pile sectionsbeing shown in dot-dash lines.

Referring in detail to the drawing, in FIG. 1 a fragment of a pile isshown and designated generally by the reference numeral 10. The pilecomprises two principal parts, an upper tubular section constituted by ametal pipe 12 and a lower tubular section constituted by a metal pipe14. The upper pipe 12 is wider in diameter than the lower pipe 14.

The upper section and the lower section are joined by a drive-fitsectional transition sleeve 16 made in accordance with the presentinvention. One section of the tran- 3,266,255 Patented August 16, 1966sition sleeve, the top section as viewed in FIG. 1, is constituted by anelongated steel pipe 20 of any desired diameter. The body of pipe 20 isof equal diameter throughout and may have any desired length suitable toresist lateral and tensional forces as well as compressional forces. Anintegral annular flange 22 is formed on one end of the body, the top endas viewed in FIG. 1, projecting inwardly and outwardly of the body.Spaced integral braces 24 support the outwardly projecting portion ofthe flange.

The other section, the bottom section as viewed in FIG. 1, of thetransition sleeve 16 is constituted by a steel pipe 26 of substantiallythe same length as the pipe 20 and is formed with an annular flange 28on one end thereof, the bottom end as viewed in FIG. 2. The body of thepipe 26 is of varying diameter tapering upwardly and inwardly, and thediameter thereof is slightly less than the diameter of the pipe 20. Thediameter of flange 281 is less than the diameter of flange 22.

It will be noted that the bottom of pile section pipe 12 is secured tothe flange 22 of sleeve pipe 20 outwardly of the body of pipe 20 of thetransition sleeve by welding 30. The top of pile section pipe 14 issecured to the flange 28 of sleeve pipe 26 outwardly of the body of thepipe 20 by welding 32.

In assembling, the pipe 20 constituting the top section of thetransition sleeve, with pipe 12 welded thereto, is lowered over thelower section, that is over pipe 26 with pipe 14- welded thereto, andforced downwardly to a force or wedge fit as indicated at 34. Thetapering shape of the body of pipe 26 permitting this wedging action.

In operation, the pile drive-r strikes the flange 22 driving the pilesections into the ground, and the entire strain of the driving operationis transferred by the flange 22 to the pipe body 20 and to flange 28 sothat the pile section pipe 12 simply is drawn down with the pipe 20.

The modified form of transition sleeve 16 shown in FIG. 5 differs fromthe sleeve 16 in that the upper section of the transition sleeveconstituted by pipe 20' constitutes the plug member and is positionedinside the pipe 26' which constitutes the socket member of thetransistion sleeve structure. Accordingly, the flange 22 of pipe 20' hasno inwardly extending portion, and the flange 28 of pipe 26 has nooutwardly extending portion. The inner surface of the pipe 26' tapersupwardly and outwardly instead of the outer surface thereof taperingupwardly and inwardly as in the transition sleeve 16 of FIG. 1, therebyproviding a force or wedge fit as indicated at 34'.
